The big problem here is that if you're at the terminal waiting on a load, you're "on-duty, not driving." This is a specific status as it relates to federal motor carrier regulations that govern the hours a driver can operate. Once you've hit 14 hours of "on duty" time for the day you can't drive any longer. Some major carriers will ask drivers to fudge this, although the rules are actually pretty strict about this. Notably, Wal-Mart has come under a lot of criticism in the past for asking drivers to mark time waiting for a truck to be loaded/unloaded as "off duty" instead of "on duty, not driving."
